IMPROVEMENT IN STATIONARY WASH-TUBS OF HYDRAULIC CEMENT.

Specification forming part of Letters Patent No. 206,000, dated July 16, 1878; application filed June 1, 1878.

1'0 all whom it may concern:

Be it known that 1, Dominic BURKE, of the city, county, and. State of New York, have invented a new and Improved Stationary Tub, of which the following is a specification:

Figure 1 is a plan view of my improved tub. Fig. 2 is a transverse section taken on line as x in Fig. 1.

. Similar letters of reference indicate colresponding parts.

My invention relates to stationar tubs for household and laundry purposes; and it consists in a tub made ofhydraulie cement,

The object of the invention is to provide a tub that is impervious to water, and will not decay or become leaky.

In carrying out my invention, I take any good hydraulic cement, preferably the kind known as Portland cement, and mix it with an equal quantity of sand, and form it into a mortar, and by means of suitably-shaped molds cast the tub, and allow it to stand until it sets, and then remove the mold and allow the tub to dry.

Instead of a mixture of cement and sand, I

may use the cement alone, and instead of making the tub in one entire piece, I may make it from a number of slabs formed from the same material and joined at the corners.

The advantages claimed for my improved tub are, that it maybe inexpensively made, and it is practically imlestructible; also, that it is capable of being molded with rounded internal corners, which add strength to the tub and facilitate cleaning.

The bottom may also be easily formed so that the water runs from all directions toward the discharge-pipe, thereby entirely freeing the tub from water.

I am aware that it is not new to make a wash-tub of soap-stone or ceramic wash-tub.

Having thus described my invention, Iclaim as new and desire to secure by Letters Patent- A stationary wash-tub of hydraulic cement, cast in molds, as set forth.

DUMINIC BURKE.
